Which of the following is a CORRECT statement with regard to the testing of a storm drainage system

This statement is incorrect because testing is typically required to ensure that storm drainage systems function properly and comply with local regulations. Regular testing helps identify deficiencies that could lead to flooding or other issues, making it an essential part of system maintenance.

While regular testing is important, the requirement for annual testing may vary based on local regulations and specific system conditions. Some jurisdictions may have different testing intervals or requirements depending on the type and complexity of the drainage system, making this statement too generalized to be correct.

This choice is inaccurate because a comprehensive evaluation of the storm drainage system involves testing both interior and exterior components. Limiting testing to only inside conductors overlooks the critical function of the entire storm drainage system, which includes external drainage elements that are equally important for effective water management.
